Seems like your mind agrees to it, but your heart doesn’t. Console your heart. It’s just one day, it’ll go away.
I, honestly, can’t figure out how this is something anyone would cry over, but I guess, women are different.
Just let it be, sis. I mean, would you really want to look sad on your wedding day over a dress? Imagine walking around with a sad face, instead of putting aside this issue and be happy on your wedding day? Which one sounds better?
Just let go of it once, and you’ll feel much better InshaAllah.
